Land heats up faster during the day than water does. As the beach gets warm during the day, it heats the air above it. The warm air rises and cool air from the ocean is pulled in to
replace it. So, air flows from the ocean to the land. At night, the land cools faster than the ocean. What most likely happens to the air at the beach at night?
The air is still
The air moves along the coast
The air flows from the ocean to the land
The air flows from the land to the ocean. At night, the land cools faster than the ocean. What most likely happens to the air at the beach at night
Answer: I believe the ocean will be cool and the land will be cool so pretty much it will be more cooler at night than the day I hope this helps.
Explanation:
What processes maintain a steady state “resting” membrane potential
Answer: Sodium-Potassium pumps (NaK Pumps)
Explanation:
So you only need to consider two things:
Are these ions mainly found on the inside or outside of the cell?
What are the ions' charges?
The location of the ions: Sodium is mostly found outside of the cell.
Potassium is mostly found inside of cells.
Sodium and potassium both have a positive charge.
So, consider this: what does sodium want to do? It wants to RUSH INTO the cell for two reasons: there is more on the outside, and the inside of the cell is negatively charged, which attracts it.
Potassium wishes to do the direct opposite. It is mostly inside the cell and wants to get out. Also, because opposite charges repel each other, potassium wishes to leave the cell.
Okay, so sodium enters the cell and potassium exits. What is it that keeps them where they are?
The sodium-potassium pumps. They take out sodium to keep it outside the cell and bring potassium back in. This is what it means to "maintain a steady state resting membrane potential."
It's three sodium ions leaving and two potassium ions entering per "pump."

1/3 (x+6)=1 plz help its due today
Answer:
= − 3
Explanation:
I think I'm not sure but i hope it helps!
Answer:
x = -3
Explanation:
Alright, so here's our equation: [tex]\frac{1}{3}(x+6)=1[/tex]
First we need to distribute the fraction into the parentheses.
I personally do this by multiplying everything inside the parentheses by the numerator then dividing it all by the denominator.
This would give us: [tex]\frac{1}{3}x+2=1[/tex]
Remember that there is basically an "invisible" 1 sitting next to the x variable, so that times 1 is well, 1, then divided by 3 is 0.33333333 or just [tex]\frac{1}{3}[/tex] . Then obviously 6 ÷ 3 = 2
Next we want to isolate the variable so lets move the 2 over to the other side by subtracting it, which gives us:
[tex]\frac{1}{3} x=-1[/tex] (what you do to one side you to do both)
Finally, lets multiply by the reciprocal of [tex]\frac{1}{3}[/tex] which is [tex]\frac{3}{1}[/tex] in order to remove the fraction. -1 * [tex]\frac{3}{1}[/tex] is just -1 * -3 which is equal to -3
Congratulations!
[tex]x = -3[/tex]
I hope this helped! Feel free to ask any questions!

Choose the 4 reasons that contributed to Mendel selecting the garden pea as his experimental subject.
A. It is not possible to perform cross-pollination in peas.
B. There were a large number of pure varieties.
C. The garden pea had a relatively long generation time.
D. The garden pea had a relatively short generation time.
E. It was one of the few plants that can be grown in a garden.
F. Garden peas can self-fertilize.
G. Earlier investigators had produced hybrid peas.
There were a large number of pure varieties and relatively short generation time. It was one of the few plants that can be grown in a garden as well as can self-fertilize.
Mendel select pea plants as a subject for his experiments because the flowers of pea plant are bisexual, self-pollinating means both male and female present on the same flower so self and cross-pollination can be done easily.
The different physical characteristics of the pea plant were easy to study. The garden pea had a relatively short generation time means it can complete its lifecycle in short period of time. It was one of the few plants that can be grown in a garden easily.
